The Imitation Game (Play for Today)

The Imitation Game (Play for Today) is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand The Imitation Game (Play for Today) rather than just read about it. In short: "The Imitation Game" is a television play written by Ian McEwan and directed by Richard Eyre, a BBC Play for Today, first broadcast on 26 April 1980. Plot It is 1940 in Frinton and 19-year-old Cathy Raine turns down a job at the local munitions factory and, much to the consternation of her parents and boyfriend Tony, joins the ATS.

Key takeaways

  • The Imitation Game (Play for Today) belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect The Imitation Game (Play for Today) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of The Imitation Game (Play for Today) from memory before moving on to harder problems.

Reference excerpt

"The Imitation Game" is a television play written by Ian McEwan and directed by Richard Eyre, a BBC Play for Today, first broadcast on 26 April 1980.

Plot It is 1940 in Frinton and 19-year-old Cathy Raine turns down a job at the local munitions factory and, much to the consternation of her parents and boyfriend Tony, joins the ATS. She is assigned to a wireless listening station, transcribing Enigma coded Morse transmissions from Nazi Germany and makes friends with Mary. After an altercation in a pub she is moved to Bletchley Park, the centre of the code-breaking operation, only to find herself cleaning and making tea. She overhears the male staff discussing the eponymous imitation game (as devised by Bletchley Park's Alan Turing). Cathy is befriended by Cambridge mathematics don Turner (based loosely on Turing) and they end up in bed together but for Turner it is a failure and he accuses her of planning it all to humiliate him. Later Cathy is caught in Turner's room reading documents relating to the Ultra programme, and she is incarcerated in military prison for the remainder of the war.

Cast Harriet Walter as Cathy Raine Lorna Yabsley as Anna Raine Bernard Gallagher as Mr. Raine Gillian Martell as Mrs. Raine Simon Chandler as Tony Brenda Blethyn as Mary Nicholas Le Prevost as Turner Patricia Routledge as ATS Officer Geoffrey Chater as Colonel in cell Keith Marsh as Factory Clerk Danny Webb as Dispatch Rider Rhys McConnochie as Technical Officer

Inspiration Writing in 1980, Ian McEwan said "initially I wanted to write a play about Alan Turing, one of the founding fathers of modern computers", but that his research provided very little material. He continued:

by this time other facts about Bletchley Park interested me more. By the end of the war ten thousand people were working in and around Bletchley. The great majority of them were women doing vital but repetitive jobs ... The ‘need to know’ rule meant that the women knew as much as was necessary to do their jobs, which was very little. As far as I could discover, there were virtually no women in at the centre of the Ultra secret. There was a widely held view at the beginning of the war that women could not keep secrets. I had come to think of Ultra as a microcosm, not only of the war but of a whole society ... By having a woman at the centre of the film (I no longer thought of it as a play), I could disguise my own ignorance about Ultra as hers. The idea was to have her move from the outermost ring to the very centre, where she would be destroyed.

Worked examples

Example 1 — a first encounter with The Imitation Game (Play for Today)

Start with the simplest possible case. Write down what The Imitation Game (Play for Today) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to The Imitation Game (Play for Today) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about The Imitation Game (Play for Today) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of The Imitation Game (Play for Today)

In research
The Imitation Game (Play for Today) appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses The Imitation Game (Play for Today) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
The Imitation Game (Play for Today) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1980 television plays, Bletchley Park, English-language television plays, so understanding it makes those chapters shorter.
In everyday life
Look for The Imitation Game (Play for Today) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
